Offshore Wind

The worldwide demand for energy is constantly growing. In the upcoming years renewable energy  will become indispensable to meet the increasing energy consumption. 

Many major companies are exploring possible ways to generate renewable energy from the most remote offshore locations. Due to these developments offshore activities are forced to adapt. With an increasing emphasis on safety and sustainability many working methods are to be revised and improved. Reducing logistic and operational costs to a minimum is the biggest challenge ahead since offshore wind farms are built in increasingly harsh environments. 

As a result of this changing offshore world, Royal Wagenborg developed a new innovative Walk to Work vessel to support maintenance operations to offshore wind farms.


Helideck

The vessel has a helideck on the aft deck with a diameter of 15 meters and is suitable for a AW169 helicopter. Advantages of an aft location: less helideck motions means higher operability. Further the heli is further away from the accommodation, which increases safety.  Next ›

Motion compensated crane

The active heave compensated crane has a maximum SWH 1,5m, liting capacity of 1,0 t and a working radius of 2,5 - 19 m. Next ›

Elevator

The elevator performs a key role on-board the Walk to Work vessel. As part of the stepless approach, the elevator provides clear unimpeded access for technicians and cargo. The elevator provides sufficient space to accommodate two euro pallets. The entrance and exits in the elevator correspond with landing area at the warehouse, gangway, helideck and weather deck.

Fast rescue Craft /...

To transfer technicians and cargo to offshore locationss, the Walk to Work vessel is equipped with a Daughter Craft and a Fast Rescue Craft as redundant transfer methods. The daughter craft is suitable for transferring 8 technicians + 2 crew and 1 ton of cargo. The daughter craft can be launched and recovered in 3,5m Hs. The Daughter Craft is capable to sail from an offshore location to port independently of the Walk to Work vessel. Next ›

Accommodation 60 persons

The modern and stylish accommodation area for staff and crew contains 60 off single MLC compliant daylight cabins of minimum 10 m2, with a dedicated sanitary unit incorporated and the following (loose) furniture. Next ›

Dynamic positioning

Equipped with Voith Schneider Propellers, Voith Online Thrusters and a Rectractable Propeller, the Walk to Work vessel has excellent DP performances, which exceed the DP performances of traditional Azimuth thrusters. Next ›

Motion compensated gangway

The gangway 3.0 is selected as the best suitable ‘walk-to-work system’, in terms of operation speed of the system, simplicity of operation, power consumption and HSEQ, to transfer technicians and cargo safely from the vessel to offshore wind turbine and oshore platforms in waves up to 3,0 metres and wind speed up to 20 m/s (38,8 knots). The gangway is mounted on an adjustable pedestal, which enables a horizontal ‘walk-to-work’.
